TRUNCATE TABLE is a Data Definition Language operation in SQL that marks the extent of a table for deallocation. This operation removes all data from a table quickly, typically bypassing a number of integrity-enforcing mechanisms.
The syntax is the same in all the SQL products such as MySQL, PostgreSQL, SQL Server, etc.
TRUNCATE TABLE TableName
TRUNCATE TABLE tbEmployees;
The data from tbEmployees will be deleted in the preceding example, but the table definitions and integrity constraints associated with it will remain.
